java - 单击时如何播放Listview项目的特定声音

Question

我创建与声音的Android词典应用程序...我有listview，当选择了一个项目，一个新的 Activity 开，里面的新 Activity 包含4 textviews和图像按钮时，textviews功能完美，但图像按钮没有。音频文件放置在原始文件夹中。如何放置被单击的项目的特定声音？
这是代码:

MainActivityJava

public class MainActivity extends AppCompatActivity {

ListView lv;
SearchView sv;


String[] tagalog= new String[] {"alaala (png.)","araw (png.)","baliw (png.)","basura (png.)",
        "kaibigan (png.)","kakatuwa (pu.)", "kasunduan (png.)","dambuhala (png.)",
        "dulo (png.)","gawin (pd.)","guni-guni (png.)","hagdan (png.)","hintay (pd.)",
        "idlip (png.)","maganda (pu.)","masarap (pu.)", "matalino (pu.)"};

int[] sounds= new int[]{R.raw.alaala,
                R.raw.araw,
                R.raw.baliw,
                R.raw.basura,
                R.raw.kaibigan,
                R.raw.kakatuwa,

    setContentView(R.layout.activity_main);


    lv = (ListView) findViewById(R.id.listView1);
    sv = (SearchView) findViewById(R.id.searchView1);

    adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,tagalog);
    lv.setAdapter(adapter);
    lv.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            String tagword =tagalog[position];

            String[] definition = getResources().getStringArray(R.array.definition);
            final String definitionlabel = definition[position];

            String[] cuyuno = getResources().getStringArray(R.array.cuyuno);

            intent.putExtra("englishdefinition", englishdefinition);



            startActivity(intent);

        }
    });


    sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String text) {
            return false;
        }

        @Override

            adapter.getFilter().filter(text);
            return false;
        }



    });

}

    @Override
public boolean onCreateOptionsMenu(Menu menu) {
    return super.onCreateOptionsMenu(menu);
}

}

DefinitionActivity.java

public class DefinitionActivity extends AppCompatActivity {

String tagalogword;
String worddefinition;
String cuyunoword;
String englishword;


@Override

    TextView cuyunotv = (TextView) findViewById(R.id.cuyunotv);
    TextView englishtv = (TextView) findViewById(R.id.englishtv);
    ImageButton playbtn = (ImageButton) findViewById(R.id.playbtn);


    final Bundle extras = getIntent().getExtras();

    if (extras != null) {

        tagalogword = extras.getString("tagword");
        wordtv.setText(tagalogword);

        worddefinition = extras.getString("definitionlabel");

    }

    playbtn.setOnClickListener(new View.OnClickListener() {


        @Override
